ANSWER: Mass QUESTION: ______________ happens when an object’s speed or direction changes. ANSWER: Acceleration QUESTION: The tendency of an object to keep moving or remain at rest is called ________________. ANSWER: Inertia QUESTION: A 4 kilogram object moving at 4 meters per second squared has a force of ______________. ANSWER: 16 Newtons QUESTION: An object hits a wall with a force of 40 Newtons and an acceleration of 8 meters per second squared, it’s mass is __________ kilograms. ANSWER: 5 QUESTION: We use this law to measure force. ANSWER: Newton’s Second Law QUESTION: This law is about objects in motion and at rest. ANSWER: Newton’s First Law QUESTION: This law explains why people who do not wear their seatbelts crash into the windshield during car accidents. ANSWER: Newton’s First Law QUESTION: To calculate pressure you should know _________________. ANSWER: Weight and Area QUESTION: As the weight of an object increases, the pressure on the object usually ________________. ANSWER: Increases QUESTION: If the weight is spread over a large area, the pressure usually ___________. ANSWER: Decreases QUESTION: If the weight of an object doubles and the area it covers doubles, then the pressure exerted _______________. ANSWER: Remains the same QUESTION: A 100 pound girl spreads all her weight evenly on a brick with an area of 10 square inches. The pressure in pounds per square inch is _______________. ANSWER: 10 QUESTION: The speed and direction of an object is it’s _______________. ANSWER: Velocity QUESTION: In an experiment, the group that tests our hypothesis is the _______________ group. ANSWER: Experimental QUESTION: We make a good prediction during this stage. ANSWER: Hypothesis QUESTION: We decide if our hypothesis is correct during this stage. ANSWER: Conclusion QUESTION: We use our senses to determine a problem during this stage. ANSWER: Observation QUESTION: We test the hypothesis during this stage. ANSWER: Experiment QUESTION: In an experiment, the comparison group is the ____________ group. ANSWER: Control QUESTION: The resistance to motion is ______________. ANSWER: Friction QUESTION: _______________ is a push or pull. ANSWER: Force QUESTION: The force that pulls towards the center of the earth is called _____________. ANSWER: Gravity QUESTION: Who was the scientist that gave us the laws of motion? (Full Name) ANSWER: Sir Issac Newton QUESTION: Which laws says that force is equal to mass times acceleration? ANSWER: Newton’s Second Law of Motion
